Natural Antiviral Supplements for Strong Immune System Support

Can dietary supplements help fight off viral infections? These natural compounds have scientific support of their role as powerful allies to the human immune system.

Natural Antivirals

The compounds listed below all have some degree of clinical support for their role as antivirals. It’s important to realize these compounds do not have comparable levels of data to that of prescription antivirals. However, that’s not a reason to discount them. There is much less incentive for research on non-patentable compounds than prescription solutions.


Monolaurin is the monoglyceride form of lauric acid — naturally found in breast and coconut milk. Many of the doctors I’ve seen over the years have recommended monolaurin as an antiviral supplement that I could take during cold and flu season.


Colostrum is produced by mammals just after childbirth. It’s referred to as “mother’s milk” and helps infants ward off infection and forms the basis of their developing immune system.

Colloidal Silver

Various metals demonstrate strong antiviral and antibacterial properties. One caveat is that they have to have a very small molecular size. These types of compounds are often referred to as “nanoparticles” but can also be found on supplement shelves as metal “colloids”.

  • HIV-1
  • Hepatitis B

Elderberry syrup is one of the latest trends in natural immune support. Research has shown certain commercial products like Sambucol to increase immune response by as much as 4500% compared to placebo (R).

Final Thoughts

Viral infections are part of human life. This year, facing the threat of the COVID-19 coronavirus, everyone I know is scrambling for an effective antiviral arsenal. Every medical professional I’ve spoken with has recommended three things above all else: wash your hands, avoid contact with sick people, and avoid unnecessary travel.
